. To allv whom it may concern:

Be it known that I, FRANEWYNNE, a subject of the Queen of Great Britain and Ireland, residing 'at Westminster, in the county of MiddleseX,Kingdom of Great Britain and Ireland, have invented Improvements in Contact-Making Devices for Use in .the Application of Electricity to 4Propel Vehicles on Tramways and Railways, fcation.

This inventionfwhich has been patented as follows: Great BritaimNo. 9,215,datedfJuly 15, 1886; Germany, No. 41,32,datedJ anuary 27, 1887; France, No. 182,077, dated March 9, 1887; Belgium, No. 78,7571), dated September 2,1887, and 'New South Wales, No. 235,'Octoof which the following is a speci- .f ber 4, 1887) has reference to improvements in electrically-propelled contact-making devices for use in the application of electricity to pro- -pel vehicles on tramways and railways accord-v ing to the mode or method in which the elec-y tricity is derived fromaproducer or reservoir of electricity, and there are employed a covered channel containing a bare main conductor of electricity (with or without a special return in the channel) and a series'of insulated con-y tactsurfacesexposed in the said channel andl f aiofiie.A

In order that thenature of my invention and the manner in which it can he `co nven.

iently carried into practical 'effect may be readily, clearly, and fully understood, I append two sheets of illustrative drawings, with the aid of which I proceed to describe my im provements.

Referring elevation, and Fig'. 2 a transverse section on the line A Bof Fignl, illustrating an electri- Y cally-propelled`contact-making device according to this invention, and herelnafter called a Vthe channel. .to collect the current from the rails,they.fare yso insulated fromV the frame of the carriery as l to prevent short-circuiting of the armature yof L f to the drawings, Eigu're'i is a sideI carrierJ Fig. 3 shows thecarrier in plan" PATENT OFFICE. s

A Figs. 4, 5, 6, and 7 are'dia-K` grammatic -views illustrating four; arrangements of 'the electrical propelling apparatus ot' the car or vehicleand carrier,whe rebythe motion of the. carrier is regulated` and'con-Vv trolled. kk.In these viewsv theV winding'of the fields on the car-motor lis `not indicatedand the armatureis indicated diagrammatically.

and'v diagrammatically inY Eig. 4, theielect'ric .motor employed is av series motor having the axis of its armature 1 arranged (by preference) f lengthwise of the closed channel in 'which'it is'v to Work.

c As shown diagrammatically inrFigvs.,and i 4, the current passes from the main conductor '6 to the pair of wheelsy .5, and afterpassing through the armature divides atthe point 10 and passes to the two windings 3 4, wound' in opposite directions on the .field-magnet.r j.` n "u Y 11 12 are carrier rolling contacts in electrical connection withthe windings 3 respectively or sliding contacts 'may'c -be used'.y The iron forming the eld-m`agnet2 is arranged to sur` round the armature lengthwise of itsaxis, as

shown in Figs. 2 and 3,' whereby externalli-nes of magnetic force,which are liable tolbe short 95 circuited andk thereby Wasted through theironV` of Ythe channel, are wholly or largely supl pressed.` 13 and 14 are the field-magnetpoles.

` 8o'. Y Sbyspirelorn The action ofthe motor for controlling the movement of the carrier in its channel for completing the car-motor circuit progressively as the car or vehicle travels along the road will be readily understood by reference to Fig. 4, in which 6 is the bare main conductor of electricity situate within a closed channel, 17; 6, an eart11retnrn eiected through the framework and wheels of the car or vehicle to be propelled andthe tram-rails; 1, the carriermotor armature; 2, field-magnet of carriermotor; 3 4, windings in opposite directions on the said field-magnet; 11 and 12,contactpieces in electrical connection with the windings 3 and 4, respectively; 15, car contact-piece; 16, ear-motor; 17, closed channel in which the carrier runs, and 18 18 insulated stud-con tacts passing through the top of the channel and provided with exposed contact-surfaces in the channel and in the roadway, substantially in the manner described in my separate application for a United States patent hereinbefore mentioned. The car contact-piece 15 is electrically connected with one poley of the carmotor 16, and is arranged to bear upon the upper ends of the contacts 18 18.

The operation is as follows; Supposing the 'car-motor and carrier to be traveling at the same velocity in the direction indicated by the arrow, and to be in the relative positionsindicated, the electric current passes from the main conductor through the wheels of the carrier to the motor-armature 1, field-winding 3, contact-piece. 11, contacts 18 18, contactpicce15, to car-motor 16, and thence to earthreturn 6% As long as the velocity of the vehicle and carrier is approximately equal within moderate limits, the course of the current above mentioned will be continued. If, however, from any cause the carrier should begin to outrnn the vehicle, the contactpiece 12 will be placed in electrical connection with the car contact-piece'l through one or more of the contacts 18. Under these conditions part of the current, after passing through the varmature 1, will pass through the e1d-wind ing 4, contact-piece 12, contact piece or pieces 18, and car-contact 15 to car-motor, and thence to earth, thereby causing the field-winding 4 to exert a neutralizing etect on the fieldwinding 3, and reducing or neutralizing the field in which the armatureworks,and thereby its propelling-power.

Should the momentum of the carrier from any cause--such as the sudden stopping of the vehiclecarry the contact-piece 11 out of electrical connection with the car-contact 15 through the contacts 18, the contact-piece 12.

will be placed in electrical connection with the car-contact 15, and the whole of the current will then pass through the iield-winding cial metallicy return-conductor, 7, laid inthe and 5 the opposite windings on the field-mag! net are shown for clear-ness each as if on a separate limb of the field-magnet, while in practice they would usually be wound together on one field-magnet.

It will be obvious that the carrier-motor maybevariouslymoditied. Thus'ashunt-momotor may be employed, as shown diagrammatically in Fig. 6, wherein the armature 1 is arranged in a shunt-circuit and provided with a separate rolling or rubbing contact, 21, which is placed in electrical connection with the carcontact 15 by the contacts 18, as shown. In other respects the operation of this modified arrangement is substantially the same as that hereinbefore described; also, instead' of plac-V ing the separate windings 3 and 4 on one ieldl magnet, they may be placed on separate magnets. In this case the two parts of the fieldmagnet 23, on which the windings 3 and 4 are wound, would be independent magnets; also, the armature may have two comm utators and double windings, which are connected, respectively, to the carrier-contacts, as shown in Fig. 7, the windings of the field'magnet in this case being in one direction only.

3 and 4 are the windings on the armature 1, and through which currents will Iiow in oppositedirections when they are in circuit. The armature is provided with two commutators, 22 and 23, and two sets of brushes, 24 and 25, one brush in each set being in electrical connection with the main conductor 6.

3 and 4 are the parts ofthe windings wound in the same direction on the field-magnet v(not shown) and currents to the rubbing or rolling contacts 11 and 12. In other respects the arrangement is similar to that shown in Fig. 4, and is similarly figured. When the whole of the current passes through the winding 3, the carrier moves forward in the direction of the arrow, as before, while when it passesthrough the winding 4 it moves in the reverse direction. When the currentis divided and passes through both windings, the one winding partly or wholly neutralizes the effect of the other, and thus regulates the propelling-power of the carrier.
